Electrical aspects of Hunterston nuclear generating station

The paper surveys the electrical-engineering aspects of the design which are considered to be of general interest, but excludes reactor instrumentation and control equipment. The location of Hunterston and its relationship and connections to the supply system of the South of Scotland Electricity Board are first described. The paper then considers the special operational features of a nuclear station and discusses the overall station-control system. The auxiliary supply system is then dealt with, and the differences between nuclear and conventional station practice are indicated, with particular reference to the extensive `essential supplies¿ system. The largest electrical auxiliaries are the gas-circulator drives, and since their design is unusual these drives are considered in some detail. The paper concludes with a description of the starting up and operation of the station.
